An autonomous system has been designed to allow the elimination of all the problems of non-drinking water. The project was motivated by the need to provide the poorest populations with access to drinking water. It is designed to be compact, to cost as little as possible and to be long-lasting.
It consists of a 25-litre receptacle to fetch the water, which is made of PET, half transparent and half black, to allow the SODIS method to be used. This is a procedure that removes most of the pathogens in water as it keeps it in the sun for 6 hours where it reaches temperatures of 60ºC. After this time, the water flows into a ceramic receptacle, which will filter the solids in suspension in 12 hours. The water purified like this will flow into a white HDPE receptacle, which has a tap. A white HDPE cap allows the process to be airtight.
Explanatory drawings have been added to assist in its use, as formally and economically the whole project is designed to be offered to charitable organisations that will take care of its distribution, explain how it works and show hygiene standards, so ensuring its use and efficiency.
